Adaptive Cruise Control problems of the 2024 Hyundai Santa Fe

When using lane following the system repeatedly warns you to pay attention, usually when in heavy traffic and after repeated warning shuts of the cruise and lane following system. When using the cruise control system the system will suggest you take a break. Both problems appear to be associated with an in cabin camera. I have driven my vehicle almost 25,000 miles and taken two cross country trips. The warning system has almost never warned me of a real problem. 99 percent of the time it is a false reading by the camera and occurs under challenging driving conditions when the last thing you need it to be told to pay attention when you truly are. During this winter I have driven more at night and the vehicle is basically un drivable because of false notifications. This has repeatedly happened in the 14 months I have owned the vehicle - the date below is just for when it happened today. I am more than willing to share details and would welcome a call.

While driving my 2024 Hyundai Santa Fe on the interstate, the “keep your eyes on the road” alert repeatedly activated even though the driver was attentive and looking forward. After multiple warnings, the system escalated to a message that the vehicle was about to be disabled, which created a serious safety concern. This happened even though the driver attention warning feature is disabled in the vehicle’s settings. The issue appears to be caused by the steering-column driver monitoring camera system falsely detecting inattention. The constant alerts are distracting, and the threat of the vehicle disabling features while driving at highway speeds is dangerous.

Everytime with acc active it activates the driver attention camera system which never works in sunlight camera reads wrong and disable acc while driving on freeway all the time due to sun reflection cant even wear polairized glasses acc never works.

System keeps saying that I am not watching the road, which I am. No eye glasses or sunglasses on. This causes the cruise control to suddenly disengage creating a safety hazard. SUV is up to date on software/firmware.

Have a 2024 Hyundai Santa Fe calligraphy hybrid with a drivers attention warning problem. The warning turns on frequently when using cruise control. When the warning beeps a few times in quick succession it actually shuts down the system, reduces speed to a crawl, and turns off the engine. This only happens while using cruise control, no issue with daw when cruise control is off. So can't use cruise control on the highway/interstate. Dealer is no help. This is obviously a safety issue when the engine turns off while driving on an interstate. Thanks.

The adaptive cruise control cannot be used while wearing certain sunglasses. The car has a driver awareness warning that is supposed to warn the driver if eyes are not on the road. It does not work with certain glasses. While driving at interstate speeds, I engaged the adaptive cruise control only to have it shut off and quickly slow down. After fumbling with different glasses while driving, I found a pair that will work with the adaptive cruise control. In the display, there is a toggle to turn off the driver awareness option, but as soon as you turn on the adaptive cruise, the driver awareness turns on again. If the driver awareness function cannot be turned off it is a safety issue. My favorite driving glasses cannot be used and I think this issue will cause accidents with the quick slowing on the highway. There should be a way to turn off the driver awareness so I can use the adaptive cruise with my sunglasses.

On a bright sunny day, the Hyundai forward attention warning (faw) shut off my adaptive cruise control while doing 70 mph, indicating that I was not focused on the road. I was looking straight ahead at the road the whole time. I later determined that the system was reacting to glare on my glasses (not sunglasses, no tint whatsoever, just glass). This led to a very dangerous condition because I was fighting with the car to determine what had happened (at 70 miles per hour), not focused on the road as I just had been prior. The system is checked as off in setup (as described in the manual) but clearly that was not the case. The driver can not shut the system like the manual says. I actually love the car, except for that "feature". This subsystem should never have been permitted into a production vehicle and, had I known, I would never have purchased. It's that big of a problem. The system appears to be very dependent upon ambient light because I never have this issue when it's cloudy, raining, or at dawn or dusk. I have complained at 2 Hyundai dealerships here in the chicago area, to a total of 4 Hyundai personnel, even sent a video my daughter recorded of me driving and exhibiting the issue. In 3 of the 4 cases, they replied the "system was performing as designed". That appears to be their mantra. The one service person replied that they had never heard that before. I guess they don't ever check reddit or write down my many complaints. I think it's clear Hyundai, as a service organization does not intend to do anything about this and, perhaps worse, the company at large has no intention of doing anything as this same subsystem is part of an extensive line of their 2025 models as well.

This vehicle has a driver attention alert system which track driver's eye and head movement to determine driver attention levels. This system can be disabled outside of using cruise control through the setup menu. However, when in cruise control, this system cannot be disabled. Unfortunately, if you're wearing sun glasses the system declares the driver is inattentive and produces a distracting aural and visual warning. If no action is taken the vehicle will automatically come to a stop, even on the freeway! this option is a driver distraction and does not allow the driver to wear sunglasses increasing the risk of motor vehicle accidents. Several customer have complained to Hyundai about this system. There needs to be driver-selectable option to enable/disable, even in cruise control mode.

The cruise control uses a camera , the is supposed to watch your eyes , to make sure you are watching the road . Unfortunately , if you are wearing glasses ( which I must when I am driving ) the light reflecting off them makes the unit think I am not watching the road . For backround, I was a highway patrol offiger for 30 years . I am very attentive to the road ahead of me . It seems Hyundai knows of this problem , which suddenly disengages the cruise control , causing rapid deceleration of the vehicle . At highway speed , this is very dangerous . It has been noted on many forums , and my dealer knows about the problem , but there is no way to disconnect the camera from the system . This is really an accident waiting to happen .

If I wear dark sunglasses, the forward collision avoidance turns off while using cruise control. If I wear lighter sunglasses, it is fine. Unfortunately, I have to wear darker sunglasses due to previous eye surgery. I am unable to utilize cruise control without compromise to my eyes because forward collision avoidance doesn’t work with darker glasses. This happens every time I test it and change sunglasses with differing shades of protection.
